Journal Article
(2018). Tiebreaks and Diversity: Isolating Effects in Lexicase Selection. https://doi.org/10.1162/isal_a_00109

A primary goal of evolutionary robotics (ER) is generalized control. That is, a robot controller should be capable of solving a variety of tasks in a domain, rather than only addressing specific instances of a task. Prior work has shown that Lexicase...
